Abstract (en)
@ A tape product which bears a visible message 16 which is changed when the tape is subjected to stress is adapted for use on containers and packages to indicate that the same container or package has been opened or the closure has been tampered with in an attempt to open the same. The message change is obtained by the tape backing 11 becoming opaque to obliterate one message 16 and provide a contrasting background for a different message 13.
